DOUBLE STEERING AND UNCLUTCHING APPARATUS FOR AVION S.

Specification of Letters Patent. Patented Feb. 24, 1920.

Application filed November 15, 1917. Serial No. 202,152.

I To all whom it may concern:

Double Steering and Unclutching Appa-c ratus for Avions, of which theifollowing is a specification.

The object of this invention is an operating apparatus for aeroplanes which allows the pilot and the passenger to separately execute the principal aeroplane steering operations, 6., vertical steering and wing warping. I

Three cases may occur in this connection:

M1. The pilot desires to steer alone.

2. Pilot and passenger steer together.

3. .The passenger steers alone.

A clutch is used to connect or disconnect the two operating devices for front and rear. This clutch can be operated independently either by the pilot ,or passenger, and is disposed so that the pilot and passenger can efiect the operation of the movements of the apparatus at any moment in the transfer of the control, and thus there is no dead point. This principle is realized by the use of a steering lever combined with a device for direct operation of the parts of the apparatus.

The invention is illustrated in the accompanying drawings which are of a purely explanatory nature.

Figure 1 is a diagram of the ensemble of the double apparatus using a clutch, according to this invention, supposing the operation to be carried out by a lever.

Fig. 2 is a vertical section of one of the two operating devi es (for the pilot or for the passenger). this section being made along the longitudinal axis of the aeroplane.

Fig. 3 is a plan view of the outer sphere connected to the operating handle.

Fig. 4 is a plan view of the operating device with the outer sphere supposed to be removed.

Fig. 5 is a vertical section of'the o erating device upon the line 55 of Fig. 2.

Fig. 6 is also a vertical section of the operating device upon the line 6-6 of Fig. 4.

Fig. 7 is a partial sectional elevation of the operating device used, 2 9;! fly heel 1 C which is on the end oi'the handl PI.

Fig. 8 is a section upon/the line 88 of Fig. 7

The warping action is transmitted by a tube R lying along the axis of the apparatus, and the rotation of this tube causes the movement of the ailerons through the countershaft and the operating shaft T (Fig.

1). This tube, or any other member. used in its place, is firmly attached to a horiaontal spherical ring A, carrying two pro- JGCtlOIlS H at 90 from the tube. These projections serve as a pivot center for av On the contrary, this sphere B may, without acting upon the vertically steering rud der. cause the rotation of the warping tube R through the ring. A opera ed by'it by means of the side bo ses H. The connected parts comprising sphere B and spherical ring A, are adapted to move around the axis of the tube R, and this tube is impelled by such movement so as to rotate in its bearin combination f longitudinal and lateral movements allows of s multaneous opera-,

tion of the stablizing device and the ailerons.

A second sphere C is disposed to r ate about the inner sphere. and one part V of the outer surface of his latter s ere serves as a sliding way. The handle P hi h is attached to C is arran ed t secure freedom of operation, by d s ri ing a cone. and for this purpos the s here C carries a set of openin s so that when it deviates in anv direction b 30 at the max um from its normal-pos tion. it shall not he ob t ted either by the warping tube R atta hed to the s herical ring A. or by the member I att ched to the inner s here B.

The problem in ouestion here is erefore to render at will the inner sphere B (used as a universal jointl sol d with the ou er sphere T o-efi'ect this, the sphere C carries on the extension line,.;.of theileveriP, a bored out boss." The inner sphere B' also carries a" bored out boss serving to guide a small piston D, and the moyement of the lattercauses it to enter the cylinder of the sphere C so as to connect the latter with the sphere B,

The movement can be effected by the use of an eccentric, a racksand-pinion;or other suitable device V In" the present case: there r is employed the rotation of a shaft bent at an angle, WltllZ-TH rod-:Wlprovided with bearings which: conne'ctxtheI crank 'ktor the piston; The 1 stroke rand length-ofthe rod are so' designedthatupon-:pfishing:therhandle P to the end-posi- 'tion; the pi sto'n moves the'sm'allest possible amount -and'theShead of the rod and the spheres:dovnot-rotate about the same point. -"lhe' crank :01 the front apparatus mount edr'near thez'pilot vandthe crankof the rear apparatusnnountednear the'p'assengers sea-t Y are"co1mecte"d by a tube G which rotates inside the warpingtubenRr This produces a" domrbl'e-cranlr shaft whose rodsf are so ad justed -thatiwhernthe front pistonzisatthe top'aof itsstrolre(apparatus inclutch); the
